Hollith, was he able to explain why you were in so much pain and why your urine was dark?
I'm glad you are home.. please take care, I know it's hard to know what to do. Being dehydrated can cause all kinds of issues. I would drink herb tea as well. Can you go to your homeopath? I wouldn't do the fruit juice if you think you have candida. You are likely potassium deficient as well.
Please remember, that all our good wishes and opinions here are just that, opinions and you need to listen to your body. I would definitely see your homeopath as this is nothing to mess with.
